What is Coccidiosis

This is a disease that is commonly found in calves from the age of one to six months but older cattle can be affected.  Bacteria damage the lining of the intestine by rupturing the cells in the lining, causing diarrhoea, which may contain blood.  Other symptons are loss of weight, rapid dehydration and loss of appetite.  Death may occur from these symptoms or complications such as pneumonia.  The bacteria multiply rapidly and infection spreads fast.


Coccidiosis is caused by one-celled parasites called Eimeria zuernii and Eimeria bovis, collectively known as Bovine Coccidia.  Bovine coccidian collects in manure and so can easily be transmitted.  The oocyst is the bacteria cell
